ABSTRACT:
The present drive for the fabric take up mechanism includes a pair of drive pulleys and a drive belt interposed in the power transmission drive and between the revolving needle cylinder and the fabric delivery rolls and the fabric take up roll. At least one of the drive pulleys is of the variable or adjustable diameter type including radially adjustable drive segments supported between opposite side pulley flanges. Radial grooves are provided in one pulley flange and spiral grooves are provided in the other pulley flange and operate in response to rotation of one flange relative to the other flange to adjust the diameter of the peripheral drive surface of the pulley. The variable diameter drive pulley is adjustable so that the speed of rotation of the delivery rolls and the fabric take up roll can be coordinated with the speed of production of the knit fabric to maintain substantially uniform tension in the knit fabric.
